A3VTS using the basic unit.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load AJ35PTF-32D datasheet PDF catalog AJ35PTF-32D PDF datasheet AJ35PTF-32D
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program AJ35PTF-32D datasheet PDF catalog AJ35PTF-32D PDF datasheet.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest AJ35PTF-32D datasheet PDF catalog AJ35PTF-32D PDF datasheet.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
The following describes the centralized control system I/O points of the estimate. Cable for extended use in multiplexing unit.Optional features of memory card (A/FX compatible).
2MB extended memory.
Applicable models: A985 (-V) /975/970/A960GOT (-B) /A956WGOT. 2 channel analog output module.
As well as analog input moodules, the A1S62DA analog output component is built into a microprocessor,
It can convert binary data into voltage or current signals,
Offset and gain are set and stored in a microprocessoor,
It also includes other features as follows:
2 output channels AJ35PTF-32D datasheet PDF catalog AJ35PTF-32D PDF datasheet AJ35PTF-32D datasheet PDF catalog AJ35PTF-32D PDF datasheet.
High resolution digital input, plus or minus 12000.
Total accuracy plus or minus 1%.
